I own a restaurant and I’m trying to setup a free Wi-Fi network for my customers. My problem is that there are busy times of the day that I don’t want people to hold up a table so that they can be on their laptop for hours. For example, during lunch time we want a quick table turnover so I would like to be able to restrict the amount of time they can use the internet. I’ve been doing some research on the subject and I have only found software that allows me to completely shut off internet access or restrict certain pages with a scheduled timer. Instead I am looking for a way to give each customer a specific time that they can be on the network. For example, during slow times we can have it unlimited and during busy times we can set the limit to 45 minutes. Is this possible? Am I asking for too much?

Thank you in advance.
